Integrating and Using NMI Payment Gateway in Laravel

• $response->successful(): Returns true if the response has a status code of 200-299.
• $response->failed(): Returns true if the request failed (status code of 400 or greater).

Other useful methods include:

fetch('https://jsonplaceholder.typicode.com/invalid-url')
    .then(response => {
        if (!response.ok) {
            throw new Error('Network response was not ok');
        }
        return response.json();
    })
    .then(data => {
        console.log(data);
    })
    .catch(error => {
        console.error('There was a problem with the fetch operation:', error);
    });

In this case, if the URL is invalid or there’s a network issue, the error is caught, and a message is logged.

In app/Models/Category.php, define the relationship between Category and Product:

public function products()
{
    return $this->hasMany(Product::class);
}

flutter run

Test the app by entering different city names and observing the weather data displayed.
